A. Group of cells
Cells - Tissue - Organ ...
If you want to know more - look for "Biological Organisation"
For this problem, the most probable and the most likely answer for this would be the second option which is cells.
When viewing, not just corks, but other things under a microscope, may it be a home-made one or of something in value or a technologically advanced microscope, small compartments would always be visible under these lenses and they are cells. Some might look like boxes but they are cells. These cells might come in many sizes, but they will always be cells. Cells are everywhere.
Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
- U is the internl energy of the system.
- ΔU is the change in U.
- Q refers to the total heat supplied into the system (include both addition and release of energy in the system).
- W is the net work done by the system.
Hence, the correct option is D.
Answer:
10 chromosomes
Explanation:

Why?
Because when this sperm (pollen) fertilizes a plant egg (?) they must end up with a total of 20 chromosomes for the plant baby.
